1 corinthians 1: Is the gospel foolishness?

Paul writes 1 Corinthians in response to a letter from Chloe’s family and a letter that the Corinthians sent to Paul asking many things. The beginning of the church is written in Acts 18, 3 years before this letter. Corinth was a great port city, gathering people from many places of the world, with their different gods. At that time, the Greek culture, Greek wisdom was very appreciated. It was common to argue about ideas and people and choose one. That is what was happening in Corinth when they were picking sides: Paul, Peter, Appolo and the Messiah. When they were taking sides, they were proud about their own wisdom, their capacity to choose the best ideas and the best people. In this scenario, Paul remembers that they were not outstanding people and even so, they were chosen by God. To be chosen by the Lord to see the beauty of the cross is far more important than to boast about oneself. Paul writes:

18-21 The Message that points to Christ on the Cross seems like sheer silliness to those hellbent on destruction, but for those on the way of salvation it makes perfect sense. This is the way God works, and most powerfully as it turns out. It’s written,
I’ll turn conventional wisdom on its head,
I’ll expose so-called experts as shams.
So where can you find someone truly wise, truly educated, truly intelligent in this day and age? Hasn’t God exposed it all as pretentious nonsense? Since the world in all its fancy wisdom never had a clue when it came to knowing God, God in his wisdom took delight in using what the world considered stupid—preaching, of all things!—to bring those who trust him into the way of salvation.
